It'll be plenty of power for 2 670's. I'm just trying to figure out the best possible value of PSU's as we get ripped off over here on components and especially PSU's.

I'm leaning toward the 860 (no i, thats a whole lot more) but the AX 850 Gold there and the Fractals are puzzling me a bit as I'm not sure what the story is with them.
Have to say I'm not very into the in's and out's of PSU's but I do want good quality (and much quieter than my current)

Anyone fancy volunteering to scour the UK/Ireland and Ukraine for for the best value high quality 850W+ preferably 80+ gold PSU? (Didn't think so)
